Abstract

(57) [Summary] [Purpose] To reduce chatter vibration and noise that occur between the wheels on the guide rail and the guide rail. [Structure] Since the outer peripheral surface of the wheel 19 mounted on the guide rail 9 is covered with an elastic member 21 made of synthetic resin or the like, it is possible to suppress chatter vibration and noise as compared with the conventional case.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stacker crane wheel for an automated warehouse.

[0002]

[Disadvantages of the prior art]

 Since the wheels of the stacker crane mounted on the conventional guide rails are made of metal, there is a drawback that chatter vibration and noise easily occur between the wheels and the guide rails made of metal.

[0003]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. In this invention, the outer peripheral surface (cylindrical side surface) of the wheel mounted on the guide rail is covered with an elastic member made of synthetic resin or the like. Here, the elastic member is a member that is more elastic than metal, in other words, a member that is softer than metal.

[0004]

[Function of the device]

 This device has the following actions. Since the outer peripheral surface of the wheel on the guide rail is covered with an elastic material such as synthetic resin, it is possible to suppress chatter vibration and noise compared to the conventional case.

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the front side of FIG. 1, the rear means the back side, the left means the left side of FIG. 1, and the right means the right side of FIG.

The rack device 1 which is erected on the floor surface has a large number of front columns 2 arranged at right and left at predetermined intervals, and rear columns arranged at predetermined intervals behind the front columns 2. It has a pillar 2 and a large number of article supporting members 4 provided on the front and rear pillars 2, and a pair of left and right article supporting members 4 which face each other without the pillar 2 constitute an article storage shelf 3. There is. A fork passage gap 5 is provided between the pair of left and right article support members 4 to allow a slide fork 15 to be described later to move in the vertical direction. The loading / unloading opening 6 of the article storage shelf 3 faces the front side.

A pair of upper and lower guide rails 9 are arranged in the stacker crane passage 8 in front of the rack device 1 so that the longitudinal direction thereof is oriented in the left and right directions, and the stacker crane 11 is guided by these guide rails 9 so as to be movable left and right. It is designed to be done. The stacker crane 11 includes a traveling carriage 12, an elevating platform 14 that can be raised and lowered by a pair of left and right masts 13 provided on the traveling carriage 12, and a horizontal movement in the front-rear direction by a well-known advance / retreat mechanism for the elevator platform 14. It has a slide fork 15 slidably provided. As is well known, the slide fork 15 pulls the article W into the elevating table 14 by performing an operation of projecting the article W downward, lifting the article W by raising the elevating table 14 and retracting the article W to the elevating table 14 side. By the reverse operation of the above, the article W can be dropped onto the article storage shelf 3 or the like.

The traveling carriage 12 has a pair of left and right wheel units 16. As shown in FIGS. 2 and 3, the wheel unit 16 includes a bracket 18, a wheel 19 mounted on a guide rail 9 rotatably mounted on the bracket 18, and a guide rail mounted on the bracket 18. It has a pair of nipping rollers 20 for nipping 9. An elastic member 21 made of synthetic resin (for example, urethane rubber) or the like is coated on the outer peripheral surface of each of the wheel 19 and the nip roller 20. Although not shown, the outer peripheral surface of the upper holding roller 23 (see FIG. 1) that holds the upper guide rail 9 is also covered with an elastic member. The wheels 19 of the right wheel unit 16 are rotated by a traveling motor 22 that can rotate in the forward and reverse directions.

[0009]

[Effect of device]

 The present invention has the following effects due to the configuration as described above. Since the outer peripheral surface of the wheel on the guide rail is covered with an elastic material such as synthetic resin, it is possible to suppress chatter vibration and noise compared to the conventional case.

FIG. 2 is an enlarged cross-sectional view of a portion A of FIG.

FIG. 3 is a sectional view taken along line III-III in FIG.
